I have them down for four decades. The 70's, 80's, 2000's, and 2010's. They disappeared in the 90's.
Only the following schools have been successful every decade from the 80's until now: Ben Davis, Dwenger, Luers, Cathedral, Chatard, Roncalli,Snider, Zionsville and Penn. Those nine pass the test for Blue Bloods. Carmel and Warren Central get a pass for the vast amount of success that they achieved every decade but the 90's. Twenty nine other programs can make a case by tweaking the criteria here and there.
It's been a fun discussion.
